To (LIZ whom, it may concern:

Be it known that I, JOHN H. JEssEN, a citizen of the United States, residing in Rensselaer, county of Jasper, and State of Indiana, am the inventor of certain new and useful Improvements in Fertilizer-Spreaders, of which the following is a specification.

My invention relates to that class of fertilizer-spreaders having a suitable receptacle for containin the fertilizer, means for discharging the ertilizer, and means for beating or pulverizing it.

The principal object of my invention is to 4provide a simple, economical, and eiiicient fertilizer-spreader.

A further object is to provide a fertilizerspreader having an endless traveling apron with a suitable device for pulverizing and discharging the fertilizer when in operation and adapted to bereadily thrown into and out of operative connection with the driving mechanism.

A furtherl object is to provide in a fertilizer-spreader having a rotatable toothed device for beating and discharging the fertilizer suitable.` movable hood and tooth or arm mechanism ooperatinlg1 with the rotatable beater-for pulverizing t e material or re- I tainin 'it, asdesired, and adapted to be A into and-'out of `operative position with relation to the rotatable beater or discharge mechanism.

A further ob 'ect IIIOVG is to provide suitable means for supporting the rotatable beater and for movin it toward and from the endless apron an the fertilizer to b'e operated y upon. 1

Other and further objects ofthe invention 'Will appear from an examination of the drawings and the following description and claims. A

The invention consists in the features, combinations, and details of construction hereinafter described and claimed. v In the accompanying drawings, Fi re 1 is a side elevation -of a fertilizer-sprea er constructed in accordance with my improvements With one of the rear supporting wheels removed toshow the mechanism for operating the beater; Fig. 2, an enlarged detail view inelevation of the mechanism for supporting and throwing the driving-gear mechanism into and out 4of ear; Fig. 3, a view of the parts shown in ig. 2, showing the gear-mechanism out/.of gear; Fig` 4 an enlarged detail view im'ievation of the pulverizer mechanism consisting of the movable hood, the movable teeth or arms connected with such hood above the rotatable beater, and the rotatable beater mounted upon the pivoted supporting-arm mechanism, a part of the gear-shaft, with its gear-Wheel for driving the beater, being removed; Fig. 5, an

enlarged'sectional elevation of the rotatable beater and the hood4 and pulverizer-arm and hooked tooth mechanism; Fig.' 6, a transverse sectional elevation taken on line 6 of Fig. 5, showing a part of the beater mechanism and the pulverizer-arm mechanism; and Fig. 7 a detail plan view of the portion of the hood, showing the manner of mounting the curved pulverizer-arms thereon.

In constructing a fertilizer-spreader in accordance with m improvements I provide a suitable receptac e or box havin side frames formed, preferably, o f metal and aving a bottom frame and tracks also formed, preferably,of metal. The box here shown comprises side frames formed of metallic plates (L, metallic side stakes b, preferably in the form of channel-irons, longitudinal metallic side sills c, formed of angle-irons,V having in` Wardly-projecting upper flange portions d, forming tracks upon which apron-rollers e support the upper lap of a traveling endless apron f, which forms a movable bottom portion for the box. The travelin apron extends from end to end of the ox, being mounted at opposite ends thereof upon sprocket-wheels g and h, which are supported in fxedrelation to shafts 'i and y', respectively, such shafts being rotatably mounted in the mainframe by` means of brackets k and Z, respectively. These shafts may be mounted in. anyordinary and well-known manner.v

Transverse beams or conneotin members 'm extend across the bottom of the or bed at suitable intervals and are formed, preferably, of metallic square or angularpipesections aving their opposite en s secured to the metallic side sills in any ordinary and well-known manner and being located between the u per and lower laps of the endless apr'on a overnientioned. Angle-irons a are secured to the top of the side plates and inthe same vertical plane with the longi,

tudinal side sills, so ,that the side frames thus form plate-girders, the top cord of which is formed by theeangle-irons n, andthe bottom cord of Whichasorm'ed by amework IOO IOS

IIO.

A front end board or plate extends from side frame to side frame and is made, preferably, of sheet metal, the front end portion of vthe' bed being o en at its bottom portion `0 for permitting t e endless a ron to pass beyond the end of the bed an around its supporting-sprockets- The rear end of the bed is open except to the extent that the beater and pulverizer mechanism, hereinafter dero scribed, serves to retain the fertilizer while such parts are stationary. g "Metallic side plates or brackets p are se-A kcured to the rear portion 'of the metallic side sills or tracks on opposite sides of the bcx'by 1 5 means of bolts g and have depending leg portions 'r in engagement with truss-rods s, secured to the side sills forward of the rear axle and to the side frames at the point indicated by thereference-letter u rearward of the rear axle;

vided at ornear their rear endsvwith suitable' journal-bearings in which the rear axle v is rotatably mounted above the truss-rod, already described. By this arrangement it will be seen `that these. supporting-plates form struts between the side sills an. trussrods and that the framework is thus trussed on each side so as to ,prevent the sagging of either of the front corners of the vehicle.

3o Brace-rods w are also secured, preferably, to

the Aside sills and extend downward and inf ward at an inclineftoward the front end of the vehicle', being secured, by means of a bolt or rivet y or in 'any ordinary and well-known manner, to the fifth-wheel, and a brace z extends upward and forward at an incline from the fifth-wheel and is secured to the front end of the side sill. rIlhe front end of the vehicleframework is supported upon a front bolster 44o or sup orting-bracket 2, which is secured,

prefere ly,to the side sills by means of bolts 3 or in any ordinary and well-known manner, 1 the lower .portion of such front bolster being secured, by means of a'bracket 4, tothe upper e 4 5 member 5 of the iifth-wheel. This upper memf ber of theifth-wheel has a horizontal bottom bearing-surface resting upon a horizontal top bearing-surface portion of a supportin member 6, which is pivotally mounted anv 5o secured to the front axle 7 A pair of front` supporting-wheels 8 are rotatably mounted upon thevfront axle, and rear supporting- `wheels 9. are mounted in lixed relation to the 'rear axle,l so that the rotation of the rear wheels will cause the axle to rotate and drive the endless 4apron which is operatively connected therewith in the manner described in my ap lication, Serial No.'257,203, filed of even 6o drives the beater and discharge mechanisms hereinafter described. l .The beater-discharge mechanism com rises a rotatabletoothed drum having a hoc and "'rearwardly-'extendinghooked teeth or arms movably mounted over suchdrum, pulver- These supporting-plates@ are pro-k ate herewith. The rear axle also izer hooks ortceth being'also `inovably mounted m the hood and adapted to cool-ieratc with the rotatable toothed drum. 'lh'e rotatable beater or drum is formed of circular end portions or heads- 10, preferably of metal, having slats or paddles 11 extending from end to end .of the drum and secured teeth of the next adjacent Slat, as indicated in Fig. 6. All of these' teeth are mounted in perforations-ll in the metallic angle memers or slats and are preferably in' engagement with the outwardly-extending ilange portions of the paddles. vThe paddle or flange portions of these slats'are adapted to carry up' and. discharge the'lighter and :finer particles of the fertilizer and spread it evenly,

and the teeth are adapt'ed'to tear and. pulverl ize' thematerial `while also serving to discharge rit from the vehicle. rEhis .beaterdrum is mounted on and in iixedrelation to a shaft 15, which is in turn rotatably, mounted in bearing-boxes 17 which are loosely or pivotally suspended from the rear upper ends of the brackets or armsl. These' arms 16 are pivotally mounted upon brackets L by means i l of shouldered pivots 41, which permit limited i pivotal movements of such pivo'ted arms and beater in a vertical lane. The journalbearings of the shaft o the beater are in depending portions 18 of the pivotally-suswhich is mounted a bearing 'box or sleeve 20, t

pended bearing-boxes 17, so that the bearingiro` which is pivotally secured to the flange pcrtion of such bracket by means of a stud 21, which extends. rotatably ythrough* a perforation in such Iflange. i

.A bearing box or sleeve '22 is pivotally mounted, by 'means of a stud 23, upon the lower portion of each bracket l, alreadydescribed, which brackets support the pivcted arms 16. y Each of" these studs extends through a perforation 24 in said bracket iiny a horizontal direction transversely" with rela-` tion to the, vehicle, so asto permit the rota-'- tionl ofV the 'bearing-benin'. a vertical piane. The stud or stub shaft\28\m`ay be mounted on a portion of the frame of the vehicle, ifdesired but I prefer the forni l shown. An 'inclined driven gear-wheel shaft of mounti'zg here 25 is rotatably mounted-'in the pivoted bearing-boxes and 22 and is provided with a bevel gear-wheel 26 at its upper rear end, which meshes with a bevel gear-wheel 27 upon the drum or drum-supporting shaft, and a lower bevel gear-wheel 28 is mounted upon the lower end of such rotatable shaft movable into and out of engagement with the bevel gear-wheel 29, which is upon and in ing-box`22 is provided with a preferably integral sleeve portion 30, which 'is loosely mounted on the stub-shaft 23, so asV to permit it to slide longitudinally of -such stubshaft and also rotate thereon, the stub-shaft being mounted in a perforation 24 in one of the brackets Z, which are attached to the side framework of the vehicle. i

` A sleeve. 31, having an annular slot 32, forming an annular end or shoulder portion 33 in engagement with a securing-lug 34, is.

. rotatably mounted upon the sleeve portion 30 of the bearing-box 22, already described, and a lever-arml 85, 'preferablyl integral with the sleeve 31, is connected wit an operatingvlever 36 by means of a connecting-rod 37 in threaded engagement with a link 38, which is pivotally'connected to such 'lever 35. The sleeve 31 isprovided with an elongated peripheral slot 39, which extends atan incline partly around and longitudinally of such sleeve, as shown in Fig. 2, and a pin 46,'

which projects from the sleeve portion 30 of the pivoted bearing-box 22, is mounted in such inclined elongated slot, so thatthe movement ofthe operating-lever 36 to its rearward position, as shown in Figs. 1 and 2,

will 'cause the gear mechanism to be thrown into gear or into `operative position, and the forward movement of such operating-lever will throw the gear mechanism out of gear and cause theparts to assume the position shown in Fig. 3'. When in gear, it will be readily seen that the movement of the vehicle forward will cause the rotation of the rear axle, and thus drive the inclined shaft 25, and thereby the rotatable beater, so that the lbeater will. revolve a direction opposite to thel direction of rotation of the supporting-wheels. The rear axle fv is also providedwith gear mechanism, by means of.

which it is operatively `connected with the endless apron, as above suggested. This In order to provide means whereby the re- I volving beater-drum may be moved toward and from the'rear portieril of the endless apron and toward and from the material to be-operated upon, the b'eater-drum-supporting arms 16, one of which is mounted on each side of the vehicle, are each pivotally mounted at their lower ends upon the brackets l. In order to accomplish this, the beater-supporting arms are each provided with a stud 41, having shoulders 42 and 43, such stud being rotatably mounted in aperforation 44, having an inwardly-projecting shoulder portion 45, adapted toengage the shoulders of the studs and limit the pivotal movement of the arms '16 and the beater-drum supported thereby.' These shouldered studs and perforations thus permit partial but prevent complete rotation of the'pivoted arms and support the arms and drum in both its raised and lowered positions.

The pivoted arms 16 are each provided with a erforated lug 46 near'their upper ends and are connected, by means of a connectingrod 48,` which enters the-perforation in such lug,`prelfer.ably with the operating-lever 36,.already described, or a similar sepgrate lever, if desired, at the front of the ve ele. The pivoted supporting-arms be- IOO ing rotated to the rearward position (shown in Fig. 4) will cause the rotatable beaterdrum to assume its rearward and lowermost position, as indicated in said fi ure. The movement of the lever 36 with t epivoted supporting-arms 16 forward 'to a where the shoulder 43 of the studwi enga e the shoulder portion 45 of the bracket' wrlll raise the rotatable beater-drum and at the same time move it forward into position to retain the contents of the receptacle when the beater-drum is not in active operation. It will be noted that the movement of the drum is forward andupward, describing the arc of a circle, the center of which is the pivot 41, and that the drum may thus be kept very close to the endless apron in both its raised and lowered positionsl` When'in raised forward position, the drum is thus enabled to retain the-contents of the receptacle, and when in lowered rear position it is sufficiently close to the traveling apron so that its revolv ing teeth will prevent any undesirable dischargeI of material between the revolviirT a ron and the endsX-of such teeth. It wi a so be noted that the forward movement of the operating-lever 36, which is connected with the lever 35 by means of the rod 37,' throws the driving-gears out of operative position and also'. throws the revolving toothed osition drum forward 'and upward at the Sametime to raised stationary position and that the rearward movement of the levers 35 and 36v throws the driving-gear lnechamsm into o`p permit such movements of the beater and the gear mechanism." y

The movement of the beater upon its supporting-arms enables it -to be movedvdown'- ward and rearward out of contact with the fertilizer before being set in rotation,and the fertilizer is then gradually brought backward toward the beater or dischar e toothed' drum to be operated upon there y. The drum may remain in rearward lowered position while in active operation. Only one connecting-rod 48 is shown; There are, how.- ever, two of these rods', counterparts of each other., one on each side of the vehicle or receptacle, and both are-secured in the same manner to pivoted arms 16 on opposite .sides of the receptacle and to the vlever 36. The lever 36 is.` mounted in fixed relation to a shaft 138, which extends. transversely across the bed or framework, being rotatably o mounted -braclfzets 139 on each side of theV frame, .and a fork 136' of the lever 36 is se` cured to the shaft on the side of the vehicle gposite that shown in Fig. 1, the to ofthe lork 136 bein indicated in dotted ines'on said Fig. 1.. his connectin -rodf48is connected to the forked portion o this-operatinglIever in the same manner as the rod shown in i ig. 1. f,

A movablehood and. ulverizer for the beater is formed of a top p ate-49, made, preferably, of metal which extends transversely across the vehicle above the rotatable beater.

Side shields'50, formed of metallic plates, are

connected to such top plate at the opposite ends 'thereof and extend downward to orbelow the upper edge of'thc box, so as to form side shields or fenders adapted to prevent the escape of the material thrown up b y the revolving beater. ffii" The' side portions of the'lfiood are provided with reinforcing irons or braces 150 and 51, the latter being. curved and extending below the upper edge of the box, so as to form a shield when the-hood is in either its raised or lowered position. This hood and ulverizer is pivotally mounted at its front ower corners upon the frame by means of studs 52, 'which extend into perforations in supportingbrackets 453, secured to the sides of the bed or i framework.- A strengthening metallic piece 54 extends along the front edge of each side fiiame, forming a suitable de ending portion for pivotall supporting theood. The ivl ots or stars 52 may bejsecured to t ese strengthening-pieces or extend into perfora-v tions in the lower portion thereof.

' sired direction.

Rearwardly and downwar'dl curved pui-- pulverizenas lndicated in Figs. 4 andl 7,

,their front ends being. arranged between transversely-extending cleats 66 and the top plate, each of such arms having a hook portion 67, extendinback of a rivet or bolt 168,

'which secures'suc cleatto the top plate-and a securely holds thef-pulverizer-armsin lace.` The lower end of'eachof these curve pulverizer-armsiis provided .With-an inwardly or forwardly projectingnhook ,portion 68 adja-' cent to theends ofthe revolvin beaten' lteeth and preferablyinstaggere relation 1 thereto, as--indicated in Fig. 6.

j AdjustableV pulverizer.- teeth 69, having hooked ends 70, are Amounted inthe hood by means of ahollow shaft 71, whichextends across the' hood near its u per front ortion and is rotatably supporte upon the v ood in brackets 72.. The vupper front ends -of the hooked teeth. or arms 69 arel mounted in this shaft,'as shown in Fig. 5, so as to swing with the rotation. of. this vshaft. This. rotatable shaft' is provided with a lever-arm 73, which is connected with an operating-lever 74 by means of a connecting-rod 75, 'which is here shown articulated or provided with joints 76 and 77, such rod being slidablyY mounted in' -the rotatable toothed beater andare secured v lto the front'npper portion of the hood and brackets 78. this means the hooked pulverizer-teeth 69 may be lowered to vertical position, as shown in dotted lines ih Fig. 4, or raised to substantially horizontal position, sio that their hooks are adjacent ,to the revolv- /ing'teeth of they beater, as 'shown in dotted lines in said figure. vThis may be accomplished by operatin the lever 74 in the deizer-teeth are in vertical-rox' lowered position, they form supports for retaining the contents en l the hooked pulver--v TCO of the vehicle when the beater is stationary.

vWhen they are in raised position, their hooked points are adjusted up or down as desired by moving the operating-lever 74 back- IIO ward or forward'A and securing it in any-'desired adjusted position byl means of the segment 79 adjacent .to such lever, the lever beingv provided with a pawl which may be of any 'ordinary known type land adapted to engage The lever, V74 and segment 79 are both mounted upon the lever 36,- as shown in Fig. 1.v By this arrangement it willA .be seen that the degree of the notches 8O of such segment.

fineness to which the material is tobe pulverized may be governed by raising or lowering the hooked points ofthe pulverizer-teeth. It willalso bernotedthat incase of any vlarge piece or pieces Y of materialbein discharged etweentherevolvng beateranfthe ulver- 'Y i'zer-t'eeth, such as cannot be puiverrzedzby the device,'the hood wil rise automaticaiy, so-as 'to permit such obstacleto be thrown out without injury to the device, and the pulverizer-teeth and hood will automatically return 'to operative position when such obstacle has been dischar ed. Such obstacles will first strike the hoo red pulverizer-teeth 69 and raise them, and the hood will be raised by such teeth, which yield suiiciently toprotect the hood from the sudden shock which it would otherwise receive. The curved xo arms are thus-entirely protected, being raised entirely out of the way of the obstacles.

The entire device with the exception of the supporting-wheels is made of metal and is of the lightest possible construction consistent with the stresses to which it is subjected in use.
